net: ethtool: add missing string for NETIF_F_GSO_TUNNEL_REMCSUM

2020-06-23T21:52:27+00:00

Commit e585f2363637 ("udp: Changes to udp_offload to support remote
checksum offload") added new GSO type and a corresponding netdev
feature, but missed Ethtool's 'netdev_features_strings' table.
Give it a name so it will be exposed to userspace and become available
for manual configuration.

v3:
 - decouple from "netdev_features_strings[] cleanup" series;
 - no functional changes.

v2:
 - don't split the "Fixes:" tag across lines;
 - no functional changes.

net: ethtool: add missing NETIF_F_GSO_FRAGLIST feature string

2020-06-19T03:37:11+00:00

Commit 3b33583265ed ("net: Add fraglist GRO/GSO feature flags") missed
an entry for NETIF_F_GSO_FRAGLIST in netdev_features_strings array. As
a result, fraglist GSO feature is not shown in 'ethtool -k' output and
can't be toggled on/off.
The fix is trivial.

ethtool: provide timestamping information with TSINFO_GET request

2020-03-30T05:32:37+00:00

Implement TSINFO_GET request to get timestamping information for a network
device. This is traditionally available via ETHTOOL_GET_TS_INFO ioctl
request.

Move part of ethtool_get_ts_info() into common.c so that ioctl and netlink
code use the same logic to get timestamping information from the device.

v3: use "TSINFO" rather than "TIMESTAMP", suggested by Richard Cochran

ethtool: add timestamping related string sets

2020-03-30T05:32:36+00:00

Add three string sets related to timestamping information:

  ETH_SS_SOF_TIMESTAMPING: SOF_TIMESTAMPING_* flags
  ETH_SS_TS_TX_TYPES:      timestamping Tx types
  ETH_SS_TS_RX_FILTERS:    timestamping Rx filters

These will be used for TIMESTAMP_GET request.

v2: avoid compiler warning ("enumeration value not handled in switch")
    in net_hwtstamp_validate()

v3: omit dash in Tx type names ("one-step-*" -> "onestep-*"), suggested by
    Richard Cochran

net: introduce the MACSEC netdev feature

2020-03-27T03:17:36+00:00

This patch introduce a new netdev feature, which will be used by drivers
to state they can perform MACsec transformations in hardware.

The patchset was gathered by Mark, macsec functinality itself
was implemented by Dmitry, Mark and Pavel Belous.

net: ethtool: require drivers to set supported_coalesce_params

2020-03-18T03:56:58+00:00

Now that all in-tree drivers have been updated we can
make the supported_coalesce_params mandatory.

To save debugging time in case some driver was missed
(or is out of tree) add a warning when netdev is registered
with set_coalesce but without supported_coalesce_params.

ethtool: set device channel counts with CHANNELS_SET request

2020-03-12T22:32:33+00:00

Implement CHANNELS_SET netlink request to set channel counts of a network
device. These are traditionally set with ETHTOOL_SCHANNELS ioctl request.

Like the ioctl implementation, the generic ethtool code checks if supplied
values do not exceed driver defined limits; if they do, first offending
attribute is reported using extack. Checks preventing removing channels
used for RX indirection table or zerocopy AF_XDP socket are also
implemented.

Move ethtool_get_max_rxfh_channel() helper into common.c so that it can be
used by both ioctl and netlink code.

v2:
  - fix netdev reference leak in error path (found by Jakub Kicinsky)

ethtool: Add support for low latency RS FEC

2020-02-19T03:17:31+00:00

As part of the implementation, provide symbolic names for wake-on-line

ethtool: provide message mask with DEBUG_GET request

2020-01-27T10:31:35+00:00

Implement DEBUG_GET request to get debugging settings for a device. At the
moment, only message mask corresponding to message level as reported by
ETHTOOL_GMSGLVL ioctl request is provided. (It is called message level in
ioctl interface but almost all drivers interpret it as a bit mask.)

As part of the implementation, provide symbolic names for message mask bits
as ETH_SS_MSG_CLASSES string set.
